Resource leak: 'input' is never closed

// You need to close Scanner. It can run, but there will be resource problems in the future.

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    String txt = input.nextLine();
    System.out.println("input "+txt);           
}

// Change to
public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    try{
        String txt = input.nextLine();
        System.out.println("input "+txt);
    } finally {
        input.close();
    }            
}
